A worthwhile encounter with another type of star: The SIRIUS system Our modular SIRIUS system is being continually extended and offers you everything that you require to switch, protect and start motors and other loads. Modular standard components match and can be simply combined – that makes working with SIRIUS so pleasant. With SIRIUS, all of the requirements from the field can be individually and cost-effectively fulfilled. The individual components distinguish themselves thanks to their space-saving design and high degree of flexibility. Further, engineering, installation, wiring and maintenance are extremely simple saving valuable time. Technically, the SIRIUS system fulfills the highest standards and is being continually innovated – for instance compact soft starter solutions, solid-state switching devices and many more. It doesn‘t make any difference as to whether a load feeder is configured using a circuit-breaker or overload relay, contactor or soft starter – SIRIUS offers the optimum solution for every application. Technology perfected: The SIRIUS design It goes without saying that the technology of our modular SIRIUS system attracts a lot of acclaim. However, just taking a look inside the cabinet is also very easy on the eyes. Outstanding ergonomics, excellent optical design and finish result in an open overall image – clearly reflected in the fact that the SIRIUS series received the iF Product Design Award. Convincing flexibility: The combination possibilities Circuit-breakers (MSPs), contactors, soft starters and overload relays can be effortlessly assembled using the SIRIUS system. The complete power range up to 250 kW is covered by just seven sizes. You only have to dock together, screw and the load feeder is ready. With SIRIUS you are never left alone: The global service network No matter where you are in the world – whether in Oslo, Nuremberg or Capetown, you can always enjoy the advantages of our unique modular SIRIUS system. SIRIUS has all of the relevant approvals worldwide and is available everywhere. Not only this, but the SIRIUS team, is always there for you in over 190 countries. 4|5 ... just like our modular SIRIUS system.

Today, the advantages of soft starting and stopping can be utilized in the widest range of applications to more simply and cost-effectively implement optimum machine concepts. For example, SIRIUS soft starters can ensure that cooling water pumps in power stations accelerate in an optimized fashion and water hammer is avoided using a special pump run-down function. 3RW44 size up to 560 kW The smoother the better Today, the three-phase motor is the drive concept most often used. In many cases, direct starting or star-delta starting is not the best solution. This is because unpleasant secondary effects are often encountered in day-to-day operation – for example, mechanical jolts in the machine or voltage dips in the line supply. Soft starters can help. While the motor is starting, soft starters continuously control the power supply to the motor – adapted to the characteristics of the driven machine. Mechanical equipment is accelerated with low associated stress levels; this has a positive effect on the operating characteristics and the lifetime of the machine is extended. Whether you wish to avoid pressure surges when using centrifugal or reciprocating pumps, ensure that conveyor systems start smoothly or you want to reduce the starting current of your saws or of a mixer – SIRIUS soft starters offer, for almost every application, the soft alternative to ensure that motors start smoothly. 6|7 Some basic information. What is the basic principle of a soft starter? Soft starters limit the starting current and starting torque. Mechanical stress, as well as line supply voltage dips, are reliably avoided. The motor voltage is reduced using phase control and is increased up to the line supply voltage within a selectable starting time. Soft starting and stopping guarantee minimum stress on the connected devices and ensure smooth production operations. Can I assemble load feeders using soft starters? Absolutely. Small fuseless load feeders can be easily assembled using motor starter protectors e.g. SIRUIS 3RV. Fused load feeders can be quickly implemented in a space-saving fashion in conjunction with thermal or electronic overload relays. This also applies to soft starters with motor overload protection: the rated motor current, trip class, and current limit can be adjusted via potentiometers. The wide range of functions of our high-feature soft starters is quickly set in a user-friendly fashion using the integrated keypad with a menu-prompted graphic display; this means that it is extremely simple to commission and troubleshoot the devices. And even more benefits. Why is closed-loop torque control the better solution? Current and voltage fluctuations when powering up: These are problems that the public utility companies have. Their equipment is stressed by the abrupt current demand. Minimize the maintenance costs of their equipment and your power bill, use the soft torque control of our highfeature soft starter. Torque time and costs associated with additional wiring are eliminated and the soft starter itself is protected against overload. In all of the other cases, utilize the advantages of our modular SIRIUS system and use our circuit-breaker or overload relay. Everything simply fits together. What are the advantages of the inside-delta circuit? With the inside-delta circuit, the phases of the soft starter are connected in series to the individual motor windings. This means that the soft starter only has to conduct the phase current, i. e. approx. 58 % of the rated motor current (line current). Our soft starters automatically detect the circuit configuration which means that, in some cases, significantly smaller devices can be used.

Is an external bypass contactor required? Increasingly more power utility companies are demanding that certain current limits are maintained when starting. This keeps the stress on the line supplies low by reducing the starting currents. The selectable current limiting of our soft starters is precisely the solution to achieve this. U IA UN IB IS t No. Thanks to the integrated bypass contact system, a bypass contactor can be completely eliminated and the power loss of the power semiconductors can be sustainably minimized. How are the connections made? All of the devices belonging to our modular SIRIUS system are connected using standard techniques. Both screw and spring-loaded terminals are standard options – other connection systems are used where available. And, when it comes to communications? IN tR Principle of the line supply phase control using semiconductor elements for soft starters M 3~ α = phase control angle US L3 -L3 ϕ α α L2 U L1 n Soft start with voltage ramp and current limiting Do all of the three phases have to be controlled? No. When operationally switching, this is not necessary for smooth motor starting with our soft alternative, two controlled phases are sufficient for the standard soft starters. But that isn‘t all – our solution not only considerably reduces the cost, but also the space taken up in the cabinet. However, if the inside-delta circuit configuration is to be used, then the third phase must also be controlled. Of course our soft starters can communicate with the outside world. For our high-feature soft starters we use a communications module for PROFIBUS DP. Are there other ways of softly starting a motor? A frequency converter can also be used to softly start a motor. However, frequency converters only make sense if, in addition to starting, the motor speed is also to be varied in operation – and this has its price. DETAIL Direct start 8 |9 It is soothing when softness always returns … With a recurrent quality, the stars revolve around the Polar star – the celestial pole in the heavens. ... SIRIUS soft starters for standard applications. Our well-proven stars are used to start motors in standard applications almost as long as the stars remain in the heavens. Just like up there, it also pays to take a closer look down here. New stars are being continually born. Just like our extended family of SIRIUS soft starters. And why does it make sense to look there? Because it is the ideal starter solution for standard applications thanks to the compact design, integrated current limiting and additional features. The new standard is called softness In the past, the direct and the star-delta start were typical starting solutions for standard applications. Today, the advantages that a soft starter offers are being increasingly utilitzed. SIRIUS soft starters, can improve the starting characteristics of escalators, elevators, conveyor belts and pumps – this is because soft starters simply start more softly than an electromechanical starter. Not only is the stress on the drive system especially reduced but also the stress on the line supply. This, therefore, plays a role in reducing the costs of plants and systems – and that from various perspectives. We have a complete range of soft starters in various sizes for almost every application. This means that you can optimally adapt your drive to the application. For instance, the SIRIUS 3RW30/31 – which controls two phases – is especially suitable for standard applications up to 55 kW. Our new SIRIUS 3RW40 with a power range from 75 kW to 250 kW can also handle sophisticated tasks the soft way. And by the way – the family of soft starters has been complemented by the smallest soft starter in the world which controls two phases – the SIRIUS 3RW3003. 10 | 11 Belt slippage on heating systems (HVAC) blowers or water pressure surges in industrial washing systems are just two of many potential problems that can occur if motors output too much power when starting. Such problems can be reliably tackled using our SIRIUS 3RW30/31 up to 55 kW (at 400 V). But the best is yet to come – the SIRIUS 3RW30/31 is the only soft starter in the world that offers the identical sizes within a family of devices. This makes it possible to easily change-over from direct to soft starting. Some basic information. What can the SIRIUS 3RW30/31 offer? Where can I use it?

Fused load feeders can also be implemented quickly in a space-saving fashion in conjunction with thermal or electronic SIRIUS 3RV overload relays. Let‘s talk about the functionality.

This is the reason that the soft starter always does an optimum job each and every time. With a size of only 22.5 mm, the 3RW3003 is the smallest soft starter in the world. At the same time, it offers all of the advantages and possibilities the “big brother“ SIRIUS 3RW30 has. How do I control the soft starter?

We have an extensive range of accessories for our soft starters. For example, fans (from size S0) that can be simply snapped on ensure that you can use SIRIUS 3RW30/31 in almost any mounting position or even at higher operating frequencies. We also have terminal covers that can be simply mounted (sizes S2, S3) for optimum shock hazard protection. And even more value added. What do I save? In the control cabinet, up to 70 % when compared to star-delta starters (example 22 kW: 55 mm wide instead of 178 mm). And it also pays to use SIRIUS 3RW30/31 when it comes to installation: It only has 3 instead of 6 motor feeder cables. 3RW30/31 Changeover made easy: SIRIUS 3RW30/31 up to 100 A. 12 | 13 SIRIUS 3RW40 is not only a new member of our SIRIUS family of soft starters – it is the shining star among the soft starters. It has an innovative control technique that up until now makes it the only soft starter in the world that controls two phases in the power range up to 250 kW / 400 V (400HP/460V). However, as a result of its especially compact design, it is also the smallest – therefore ensuring a space-saving and transparent control cabinet layout. It is more than just a supplement to our SIRIUS 3RW30/31 series of soft starters that control two phases. What are its distinguishing features? Some basic information.

What is different in comparison to SIRIUS 3RW30/31? The starting voltage, starting and stopping times of the voltage ramp, and the current limit can be continuously set in a user-friendly fashion using rotary potentiometers. Just like SIRIUS 3RW40 has all of the advantages of the SIRIUS 3RW30/31. The rated motor current, the 3RW30/31. It also offers more functions the release time, and the motor overload and has a unique feature in this power range function reset are handled, just like the – it controls two phases.

In this case, you don‘t have to learn anything new. symmetry, when the power semiconductors are controlled in both of the controlled phases, then the DC current components can occur. For starting voltages of less than 50 %, this can result in a significant amount of noise at the motor. “Polarity Balancing” reliably eliminates these DC components while the motor starts. It generates uniform motor starting characteristics regarding speed, torque and current increase. In this case, the acoustic quality of the starting operation has almost the same quality as that of a starting device that controls all three phases.

Thanks to the integrated And even more value added. motor overload protection, according to IEC 60 9474-2, you do not require an additional overload relay – therefore saving space in the control cabinet and wiring in the load feeder. An intrinsic device protection prevents the thyristors from being thermally overloaded avoiding damage to the power module. The thyristors can be optionally protected against short circuits using SITOR semiconductor protection fuses. Current spikes at power-on are also reliably avoided thanks to the adjustable current limiting. What accessories are available? We offer an extensive range of accessories for our soft starters. For instance, frame terminal blocks, accessories for mechanical reset, a module for a remote reset, a sealed cover, or terminal covers that can be simply mounted to provide optimum shock hazard protection. 3RW40 High functionality for a low price – SIRIUS 3RW40. 14 | 15 For a soft but powerful start … When a Supernova explodes, things get pretty hot up there with several million degrees Celsius – as was the case back in 1987. ... our high-feature soft starter.

It is good to know that for applications with higher requirements, we have our extended family of high-feature soft starters SIRIUS 3RW44 size up to 250 kW with a compact design, closed-loop torque control, graphic display, communications link via PROFIBUS and many more powerful features fully in- SIRIUS 3RW44 size up to 560 kW tegrated into the modular SIRIUS system. Our family of soft starters has been expanded by the SIRIUS 3RW44 series – thus making soft starting and stopping also attractive for difficult starting operations. The highest degree of functionality in conjunction with the simplest operator control and extensive diagnostics functionality packaged in a sophisticated design are only just some of the reasons why the SIRIUS 3RW44 is a valuable alternative to starting and stopping motors using a frequency converter. 16 | 17 Packed with the highest degree of functionality, the SIRIUS 3RW44 also handles difficult starting operations simply but softly. Thanks to its innovative closed-loop torque control, it can be used to start drives up to a power rating of 710 kW at 400 V in a standard circuit configuration or up to 1200 kW at 400 V in an insidedelta circuit configuration. The functionality designed for simple handling promises to offer the non plus ultra when it comes to operator-friendliness. Some basic information. What can the SIRIUS 3RW44 offer? Due its extremely compact design, the SIRIUS 3RW44 is completely in-line with the long family tradition of SIRIUS soft starters.

www.siemens.com/softstarter The specified motor power ratings are only approximate values. Soft starters should always be selected and dimensioned using the rated motor current as criterion (rated operating current). All Siemens soft starters are designed for normal starting conditions (moment of inertia of the total drive JLoad < 10 · JMotor). If required, a larger device must be selected for conditions that deviate from this or for increased switching frequency. We recommend that the “Win-Soft Starters” selection and simulation program is used. Motor power data based on DIN 42973 (kW) and NEC 96/UL508 (hp).
